風量調節機構。 In the air volume adjustment mechanism, a damper mechanism 2 is placed in the middle of the flow path of the duct 1, and the cross-sectional area of the flow path is changed by rotating the damper member 2' to adjust the air volume.
The duct is constituted by a pipe 1A on the upstream side and a pipe 1B on the downstream side with the damper member in between,
An air volume adjustment mechanism characterized in that the connecting portions of the upstream and downstream piping are enlarged to have an arc shape larger than the rotation radius of the damper member and formed continuously and integrally.
